Im so sorry for your losses. The first thing you must do, is make it secure. Are you feeding them outside the run? If so...you will have to place all thier feeders and waterers in the run, to catch them. Once in the run, catch them and place them in the coop...with food and water. Just make sure its not too hot in there, and that there is air moveing. Leave them in the coop for a few days. Remind them this is where "home" is. They are pretty smart, and will learn fast.
